Oil & Gas

Technology integration for oil and gas environments.

Oil and gas operators need process, safety and security systems to remain available and segregated across hazardous and remote environments.

What makes it hard

The challenges we are asked to remove.

  • Hazardous-area classifications that constrain equipment selection, cabling routes and installation methods
  • Process control networks that must remain segregated from corporate IT without losing operational visibility
  • Remote terminals and unmanned assets with limited bandwidth and no resident technical staff
  • Legacy SCADA and telemetry estates operating alongside modern IP-based systems
  • Commissioning windows constrained by shutdowns, turnarounds and permit-to-work regimes

Sector context

What makes oil and gas technology different in the UAE

Area classification governs everything that follows. Places where an explosive atmosphere may occur are classified into zones, and IEC 60079-10-1 sets out how that classification is made. The result governs equipment: IEC 60079-14 covers the design, selection and erection of electrical installations in explosive atmospheres, so an enclosure or a cable gland is selected by protection concept and zone before it is selected by function. Protection is layered separately from control, and IEC 61511 sets the integrity a protective function has to achieve and the approval required before a change affecting it.

Operator specification usually sits above the international standard. Major operators here publish their own engineering and HSE standards and mandate them contractually, so equipment satisfying IEC 60079 can still fail the specification governing the site, and the applicable standards are worth naming before anything is priced. Offshore and remote onshore facilities add mobilisation, permit and marine access constraints that dominate the programme. A buyer should expect documented evidence of competence before any work inside a classified area is priced, and should expect the security requirements of the operator to apply to cameras and access control as much as to the process systems.
